SNOBECK WINDOWSTRUCTURE Filed July 20, 1955 United States This invention relates toimprovements in window structures and more particularly relates towindow structures in which the window sash may slide along its guidewaysto open and close the window and may swing inwardly for cleaning fromthe inside and for ventilation purposes.

An object of my invention is to provide a novel and improved draft-freewindow structure mounting the win dow sash to be pivoted to an openposition for ventilation purposes and to afford a means for washing thewindow from the inside.

Another object of my invention is to provide an improved structure andarrangement for guiding a sliding window sash for movement along awindow frame, wherein the window sash may be detachably locked fromsliding movement along the window frame and may be pivoted about thelocking means therefor, to provide a means for pivoting the window forventilation purposes and for washing the window from the inside.

A further obiect of my invention is to provide a win dow sash and frametherefor, wherein the guideways for the window sashes are in the form ofrecessed slideways extending vertically along the jamb of the frame, andwherein the slideways are engaged by guide rails recessed, within thesash and extensible therefrom into engagement with the slideways toafford a draft free structure accommodating the window to be readilyraised and lowered.

Still another object of my invention is to provide a simple andefficient form of window structure having parallel spaced guidewaysextending along the jambs of the window frame and opening toward thesash, with slide rails recessed within the opposite rails of the sashfor extension within the guideways, wherein the sash is provided withlocking bolts released by the slide rails upon extension thereof fromthe sash, and engage'able with cooperating sockets in the guideways uponretraction of the slide rails within the sash, soas to afford a meansfor locking the sash from vertical sliding movement and a pivot supportmeans for the sash, accommodating the sash-to be pivoted from the insidefor ventilation purposes andfor washing from within.

These and other objects of my invention will appear from time to time asthe following specification proceeds and with reference to theaccompanying drawings where- Figure l is a transverse sectional viewtaken through a window structure constructed in accordance with myinvention, and showing the window sashes in outwardly extended pivotedpositions by broken lines;

Figure 7 is a sectional view taken substantially along line VIIVII ofFigure 6.

In Figures 1 and 2 of the drawings, a windowframe structure is shown,which may comprise a lower sill 10, a top head rail 11, and parallelspaced jambs 12, 12 having guideways 13 and 14 extending verticallytherealong.

The guideway 13 may have the usual blind stop 15 extending along theouter side of the window frame inwardly from the jarnb thereof, and maybe stepped to be slidably engaged by a stepped side rail 16 of an upperwindow sash 17. The guideway 14 for a lower window sash 19 may have ashoulder 20 formed therein, along which the outer side of a side rail 21for the lower sash may slide. The guideway 13 may also be stepped, to beslidahly engaged by an outwardly stepped portion 23 of the side rail ofthe lower sash 19.

It should here be understood that the shoulder 29 takes the place of theusual parting strip to avoid interfering with inward swinging movementof the upper sash 17.

Along the lower part of each guideway 14 and recessed within the ,amb 12is a channel slideway 24, extending therealong for the full length ofthe guideway 14 and adapted to be slidably engaged by a retractibleslide rail 25, extensible from a channel-like housing 27, recessedwithin and extending vertically along each vertical side rail 21 of thelower sash 19.

It should here be understood that both side rails of the sash 19 have asimilar channel-like housing 27 within which may be retracted a sliderail 25, and that since the construction on both sides of the window isthe same, one side of the window only,.need herein be shown anddescribed in detail.

The channel slideway 24 is shown as having a plurality of sockets 2?, 29recessed therein to be engaged by a bolt 30, slidably mounted in theside rail 21 of the window sash, to lock the sash from vertical movementalong the guideways 14, 14 and accommodate the sash to be pivotedinwardly about the axes of the bolts 30, 36.

Each bolt 30 is shown as being slidably mounted within a socket 31extending inwardly from the base of the channel-like housing 27, and inan outwardly spaced cover plate 33 for the upper portion of saidchannel-like housing. The bolt 3b is likewise shown as extending througha release arm 34 secured thereto as by a pin 35. The release arm 3:4 isshown as depending from the bolt 30 into position to be engaged by aninturned upper end 39 of the slide rail 25 to retract the bolt 30 fromthe socket 29 as said slide rail is extended into engagement with theslideway 24, as will hereinafter be more fully described as thisspecification proceeds.

A spring 36 is shown as being interposed between the inner wall of thechannel-like housing 27 and the inner side of the arm 34 to bias thebolt 30 in an extended position relative to the side rail 21 of the sash19 to engage the socket 29.

Each slide rail 25 is shown in Figures 3 and 5 as being mounted in thechannel-like housing 27 for extensible movement therefrom on parallellinks 40, 4%. As shown in Figure 5 the slide rail 25 is of achannel-like form, opening toward the base of the housing 27 and havingthe links 4%, dii'extending within the open portion thereof andpivotally secured thereto as by pivot pins 43, 43. The inner ends of thelinks 40, 4'0 are shown as being pivoted to the base of the housing 27on pivot pins 45, 45, ex-

a'rossco tending through the outwardly extending vertical legs of anglebrackets 46, 46. Said angle brackets are secured to the base of thehousing 27, as by rivets 47.

The housing 2.7 is shown as having parallel inwardly extending guideportions 49, 49 spaced inwardly from the outer walls thereof andslidably extending along opposite sides of the slide rail into slidingengagement therewith, to seal the sash to the window jarnb.

A tension spring 59 is shown as being provided, to bias the slide rail25 into an extended position from the chan nel-like housing 27. Asherein shown, the spring 50 is secured at one of its ends to an ear 51extending outwardly from the base of the channel-like housing 27 and atits opposite end to an ear 53 extending inwardly from the rail 25.

The lower end of the rail 25 is shown as extending angularly inwardlytoward the base of the housing 27, and as being guided in an arcuateslot 55 formed in a face plate 56, which may be secured to the outsideof the side rail of the sash. As herein shown a pin 57 is connected withthe lower end of the slide rail 25, and extends outwardly through thearcuate slot 55, and has a key 59 on its outer end. The key 59 is of aconvenient size and is in position to be grasped by the hand, to retractthe slide rail 25 within the channeldike housing 27 upon downwardpressing movement on said key. Downward pressing movement on the key 59will release the upper inturned end portion 39 of the slide rail 25 fromthe arm 34 and in turn release the bolt 3% to engage the desired socket2 9, to lock the sash from vertical movement and to form a horizontalpivot therefor. The pin 57 may be threaded on the slide rail 25, asshown in Figure 4 and the key 59 may be turned to tighten said keyagainst the face plate 56 and hold the slide rail 25 in a retractedposition.

The upper sash 3.7 is shown as having a channellike housing 6% recessedwithin and extending along each side rail thereof. The channel-likehousing at is like the housing 27 except that it opens from the bottomof the sash to afford a means for retractibly moving a slide rail (itwithin said housing to release a bolt 63 to engage a sec t in a channelslideway 65 for the upper sash. .ueway 65 extends vertically along theguideway 13 for the entire length thereof.

The slide rail 61 is like the slide rail 2;; and is pivotally mountedfor retractible movement within the housing 69 on parallel links 66, ashorizontally pivoted to the base of housing on angle brackets 67, 67. Atension spring 69 is also provided to extend the slide rail 61 from thehousing at within its cooperating channel slide 65.

The slide rail 61 has an inwardly inclined lower end portion 75) towhich is pivoted a depending link 71 on a pivot pin 72. The link 7% isshown as extending through a slot 75 in a lower intermediate wallportion 76 of the housing 6t) and as being retained between verticallyspaced ears 73 74 extending inwardly from the base of the housing 6G,when the slide rail '71 is in a retracted position. A ring 77 is shownas being connected to the lower end of the link 7t"? and dependingtherefrom. The ring 77' ailords a means to be grasped by the finger toretract the slide rail 61 from the slide 65 into the housing 63, andrelease the bolt 63, to engage a socket 64. The ring 77 may also holdthe rail 61 in a retracted position when abutting the bottom of the ear7 4.

It should further be noted that the rails 25 and 61 are biased intoengagement with the respective channel slideways 23 and 65 withsufiicient frictional resistance to hold the window in position duringraising or lowering thereof, but still enable the window to be easilyraised and lowered.

It may be seen with reference to Figure 1 that when it is desired toswing the sashes 17 and 19 outwardly, that the lower sash 19 is moved tothe upwardly extended position shown by broken lines, to accommodate thebolts 30 in each side rail of the sash to engage the upper sockets 29,29. The upper sash is likewise moved downwardly along its guideway toaccommodate the bolts 65, to engage tr e lowermost sockets 64, 64-. Whenthe sashes are in these positions the slide rail 25 is released from thepin 33 by depressing the key 57 downwardly along the slot 55 toaccommodate the bolt 30 to enter the socket 29.

The fingers are also inserted within the rings 77, 77 to retract theslide rails 61, 61 within the housings 69, 60 and accommodate the pins63, 63 to engage the corresponding sockets 64, 64.

When it is desired to maintain the sashes l6 and 19 in the inwardlyhinged open positions shown by dotted lines in Figure 1, a toggle linkor other locking link arrangement (not shown) may be provided to holdthe sashes in the desired angular positions.

it may be seen from the foregoing that a novel and improved form ofwindow frame structure has been provided which the window is sealed by aslide rail extensible within a channel guide extending along the windowjamb, and is locked by a spring urged bolt which is automaticallywithdrawn when the rail is extended into the channel for verticalmovement therealong.

it may further be seen that the window sash may be slidably moved alongits frame and held in position therein by engagement of the rail withthe channel guide and may readily be pivoted about its locking bolts, toopen the window, for ventilation and to enable the window to be cleanedfrom the inside.

it will be understood that the device of my invention is adapted foreither metal or wooden sashes and frames, and that while two forms ofreleases are herein shown, the same releases are suitable for use ineither the upper or lower sashes.

It will be understood that modifications and variations may be elfectedwithout departing from the spirit and scope of the novel concepts of thepresent invention.
